Changes since v0.4.0.

Early release. In SemVer terms, anything may change before 1.0, including file formats, the HTTP API and settings, though changes to .ochx and .och files will come with conversions.

New

  • Full screen (#234, [#237]): Full screen in the timeline's toolbar, or F with the timeline focused, makes the timeline cover the window. It works even where the browser refuses its own full screen, such as an embed without allow="fullscreen". Dialogs still open above it. Exit full screen or Escape returns to the page.

Fixed

  • One label per ruler tick (#241, [#244]): while two graduation levels crossfaded, a tick could draw both of its labels on top of each other, such as "20:00" and "20h" reading like "20000". Each tick now draws one.
  • Readable offsets deep in a large unit (#242, [#245]): zoomed far into a display that counts in a large unit (millions of years, say), the ruler's offset labels read like "Δ 1.446e-13 million…", from a fraction of enormous integers. They now count in the largest smaller unit the view spans ("Δ 7 s", "Δ 250 ms", "Δ 3 days"), from a round base, and still parse back exactly.

Also

  • An explainer video series and eight vertical shorts, with their scripts, sources and render pipeline, are in publicity/ (#243, [#246], [#247]).
  • CI jobs have time limits, and a flaky WebKit check waits for layout (#239).
